LOS ANGELES (CBSLA.com) — The Los Angeles County Board of Supervisors unanimously approved agreements Tuesday to increase salaries for several groups of county employees.

Under the agreement, salaries for firefighters, sheriff’s deputies, and other county workers will be raised by 10 percent over the next three years, according to officials.

The pay raises will also take effect for county criminalists, peace officers, custody assistants, coroner investigators, probation directors, supervising child support officers and assistant deputy district attorneys.

The timing will vary for each bargaining unit as to when employees will receive a 3-percent increase retroactively to September or October.

A second 3-percent increase will occur within the 2016-17 fiscal year. Two increases totaling 4 percent will take place in the 2017-18 year.

The deal also gives workers an extra week of vacation and a new paid holiday, Cesar Chavez Day, which the county will begin recognizing starting in 2017.

The unions have already ratified the agreements.

However, Service Employees International Union Local 721, which represents more than 55,000 county employees, has yet to ratify the contract with officials.
